What does "pressure testing" involve in pipe repairs?

"Pressure testing" in the context of pipe repairs primarily involves checking for leaks by pressurizing a section of the piping system. This process is critical to ensure that any repairs made are effective and that the integrity of the pipeline is maintained. During pressure testing, the pipe is filled with a test fluid, often water, and then subjected to a specified pressure level. By monitoring the pressure over time or inspecting the pipe for any signs of leakage, technicians can identify weaknesses or potential failure points in the system.

This method is an essential quality control step in pipe installations and repairs, helping to prevent future issues that could lead to service interruptions or environmental hazards. It does not focus on sealing pipes, cleaning, or increasing water flow, which are different processes altogether involving distinct techniques and purposes. By concentrating on detecting leaks and validating the durability of the system, pressure testing supports reliable pipeline operation.
